T0 a/ZZ whom, it W1/ay concern.-

Be it known that I, FRANCIS H. RICHARDS, a citizen ofthe United States,residing at Hartford, -in the county of` Hartford and State ofConnecticut, have invented certain new and useful Improvements inyCarving- Machines, of which the following is a spec1- fication.

This invention relates to machines for. carving repeat ornaments or arepeating series of. ornaments on wood, moldings, or the like, whereintwo or more tools or sets of tools, one or'more for incising the contourof or others for making one ormore cuts meeting said incision orincisions, coact to carve the desired design, and moreparticularlyrelates to a machine of the character just bers may beoperated upon simultaneously.

Myinvention consists in improved mechanism for actuating a plurality of'tools at high speed to operate upon a plurality of stock members,improved Ineans for feeding to said tools a plurality of stock members,andimproved and compact structure, practical combination and mechanicalorganization for greatly increasing the output ofa machine of thischaracter.

It is highly desirable where a great quantity of stock is to be operatedupon, and isone object of ythis invention, to provide means which kwillcomplete said operation upon as great a quantity of said stock aspossible in a given time and also -to construct a machine capable'of anincreased output which will be compactly or anized and `occupy as littlespace as -possib e commensurate with the work required to beaccomplished( 'I have illustrated my invention as empanyingdrawings,in'whichlike reference 'characters referto like parts throughout theseveral views. y

Figure 1 is a `plan view of a carving-ma side elevation showing sidewall and base broken away; Fig. 3, a partialv sectionon line a; ofl Fig.1; Fig.,4, a partial section on line y y of Fig. ,1, Fig. 5, a detail inperspective of one ofy the feed-'roll mechanisms; and' Figs. 6, 7, and 8respectively, time-charts of the movements of the tools having thegreater travel,the tools having the lesser travel, and the stock-feed.

Referring to the drawings, the machine is l mounted and lassembled upona` box-like frame A. A stock-bed B is longitudinally mounted on the topof the frame A. The stock-bed Bv is provided with a plurality ofparallel stock-guides 2,. running longitudinally of' said stock-bed. Thestock-guides 2 are formed in the upper surface of the stockc bed B andare ordinarily rectangular in crosssection. I have shown three suchstocke guides 2 set parallel to and having the'same angular relation tothe top.` of frame A. The stock-guides 2 areV angularly-inclined fromthe horizontal to allow of the operation of the tool-carryingr beams, ashereinafter described.A A shaft 3 is mounted longitudinally of the frameA and parallel with the stock-guides 2 in bearingsy 4 in said frame. Theshaft 3 projects without the frame A,

and a driving-pulley 5 is mounted upon jits projecting portion. Uponthat portion of shaft 3 lying entirely within the frame A areconsecutively mounted from left to right (referring to Fig. 2) a spiralgear 6, an

eccentric 7, and a crank 8.

Mounted in bearings 9 in the frame A above and at right angles totheshaft 3 is a shaft 10, carrying a spiral gear 11,meshin with spiral gear6 on shaft 3. The spiral gears 6 and 11 being of equal diameter, theshaft 10 is driven at the same speed las the driving-shaft 3.

Referring to Fig. 4, the shaft -loprojectsV withoutthe frame A at itsleft end, andupon its projecting portion is mounted a peripheral cammember'12. frame A shafts 13 are mounted in bearings 14 in the stock-bedtransversely of ythestockbed B.` Eachfof lthe shafts 13'is provided`with feed-rolls 15, one for each stock-guide,

the periphery of which feed-rolls 15 extend -slightly above lthe bed oftheir respective vstock-guides through apertures in the stockbed B.Mounted in spring-pressed bearings 16 onv the stock-bed B, parallel withand directly above the respective shafts 13, arel yshafts 17. Upon eachof the shafts 17 are mounted presser-rolls 18, one foreachstock- 'guide,and which presser-rolls 18 are adapted to bear upon the stock at a pointdirectly above the corresponding feed-roll 1.5, and having activeperipheres of corresponding diameter to that of said feed-rolls 1,5. Theshafts 17 respectively carry gears 19, respectively meshing with anddriven by gears 20, respectively mounted on shafts 17; The gears 2O areeach provided vwith an'internal At either end of the IOO rack 21, inwhich rack gears 22, one-quarter the diameter of said racks, mesh. Thegears 22 are mounted upon shafts 23, journaled in bearings 24 on theframe A. Each of the shafts 23 carries a ratchet-wheel 25, the teeth ofboth of said ratchet-wheels being pitched in the same direction. theshafts 23 is a rocking arm 26, carrying at one end a pawl 27, engagingthe ratchetwheel 25, and connected together at their other ends by alinkbar 23. The connection between the rocking arms 26, accomplished bythe link-bar 28, is such that the rocking' arms 26 will always remainsubstantially par` allel. A connecting-rod 29 is pivoted at one of thejoints between the link-bar and the rocking arms 26 and is bifurcated atits free end andembraces the projecting portion of the shaft 10 adjacentthe peripheral cam 12, retained in such embrace by a collar 30. A roller31, mounted upon a stud 32, fixed to the connecting-rod 29, is adaptedto roll upon the periphery of the peripheral cam 12 and actuate said rod29 in conformity with said cam. The connecting-rod 29 is retracted by a.spring 33, causing the roller 31 to travel on the face of cam 12 an ilpreventing the bifurn cated portion of rod 29 from disengagingwit-h theshaft 10.

The operation of the feed and presser roll mechanism 4is' as follows:The rotation of driving-shaft 3 is imparted to shaft 10 through spiral.gears 6 and 11 at an `equal speed. T he cam 12 is a one-quarterthreequarter came-fthat is, it moves the connect ing-rod 29 through theroller 31 forward duringone-quarter revolution of the shaft l0, rockingthe rocking arms 26, which, through the engagement of the ratchetwheels25 by the pawls 27, rotate the shafts 13 and the feed-rolls 15 thereonand the shafts 17, geared thereto and carrying presser-rollsl 13,

during said forward movement, while during the Aremaining three-quartersrevolution of the shaft 16 the connecting-rod 29 and the rocking arms 26are allowed to be retractedv by the spring 33, the pawls 27 riding overthe ratchet-wheels 25 and imparting no motion to the feed andpresserrolls. The feed-rolls 15 are provided with toothed'or roughenedactive peripheries to better grip the stock,

and the presser rolls 1S, moving in unisontherewith, press the stockdown upon said active perlpheries. y

Referring to Fig. 3, 1n upstandingears 34 of the frame A a pivot-stud 35is mounted` parallel to the stoc -guides 2. A pivot-stud l 36 is mountedparallel to the stock-guides in upstanding ears on extensions 37 of theframe A and also lies in the same parallel plane to the stock-bed B asthe pivot-Stud. 35. A pivot-stud 39 is similarly mounted in upstandingears on extensions 33 and 56 of the frame A. Two arms 40 and 41 ofexactly equal lengths between pivot centers Pivotetl upon each of and 41are set so that at the center point of their oscillation produced bycrank 8 they will be substantially perpendicular to the cut desired tobe made by tools carried upon the vbeam 42. The beam 42 is providedwith. a multiple-tool bed 45, which depends there from and conformssomewhat closely to the cross-section of the stock-guides 2. Thetool-bed 45 has a tool-face.perpendicular to the stock-guides, andtool-clamps 46 are arranged thereon for holdingthe Shanks of a seriesof. tools 47. Each of the tools 47 is adapted to engage and incise astock member lying in the corresponding stock-guide 2, substantially`parallelly of one wall ofthe stock-guide 2 as thek beam is rocked by thecrank 8. All of the tools 47 incise the se\TF eral stock memberssimultaneously and in the same degree. The arms 40 and 41 should be ofsuch length that the oscillation necessarily given to them to producethe de sired length of incision of the tools 47 will take place inan arcso closely approaching a straight line as to be almost imperceptible,and the tools 47 may be so formed as to. admit of no disastrous resultsfrom this arc motion in making the incision. The tools 47 should remainwithin the peripheries of the stock about three-fourths of a 'revolutionof the, main shaft 3 and without one-fourth. Two arms 43 and 49 ofexactly equal lengths between pivot centers are respectively pivoted topivot-studs 35 and 36 and are each connected to a beam 50 by pivots 51and 52, the distance between tliecenters of pivots 51 and 52 beingexactly equal to that between the centers of pivotstuds 35 and 36. Thisconstruction renders the beam 50 translationally movable toward and awayfrom the stock-guides 2 and at all times -equidistant from the severalstock-guides. The arm-48 is extended below the pivot-stud 35 and isconnected by eccentric-rod 53 and straps 54 with the eccentric 7. Thearms 44S and 49 are set 'sothat at the center point of their oscillationproduced by eccentric 7 they will be substantially perpendicular to thecut desired to be made by tools carried upon the beam 50.

I have seen iit to operate the beam 50 by. an eccentric, as the throwrequired in this particular machine is very short, being much lessv thanthat required in beam 42; other- Ico I IIO wise the beams 42 and 50 areactuated in substantially the same manner. The beam 50 carries aplurality of tools 55, arranged in like manner, but at an opposing angleto the tools 47 on the beam 42. The paths of the tools 47 land 5 5 crosseach other at right anproiile of the stock during three-quarters of ashaft.

`lated parallelograms.

revolution of' the drive-shaft and simultaneously remain entirelywithout said proiile during one-quarter revolution ot the drive- Thetools 47 make simultaneous incisions in each of the stock members, whileat the same time the tools 55 simultaneously make meeting incisions ineach stock member, n registering with somek previously-made incision ofthe tools 47, thereby cutting out a chip and forming an ornamentalcharacter upon each of the stock members. The cam l2 is set upon theshaft 10 to actuate they feed rolls 16 during that quarter-revolution ofthe drive-shaft during which the tools 47 and 55 are entirely withoutthe proiile'of the stock members. These relative movements are clearlyshown in Figs. 6, 7, and 8 taken together, in which the curves ofmovement of these several parts are illustrated. i

It will be observed that the tools are set parallel to one another on atranslationallymoving beam mounted transversely oi a plurality ofparallel stock-guides lying` in a single plane parallel to said beam. Itwill also be observed that the translational movements given therespective beams have convergent directions and that the tools mountedon the respective beams are positioned thereon inclinedsubstantially insaid directions, depending below the beams,with their cutting edgeslying in the lines or" intersection. of the planes of their movement atthe extreme limit of their downward motion.

The fcutt er-carrying beams, their Vsupport-` ing connections, and theframe form articu- In practice it should be desired to maintain theparallelism of these parts; butI wish to point out and eX- pressly statethat deviation from the eXact parallelism of these parts which mightarise from incorrect construction or brought about by any particularshop practice which would produce a practically operative machine wouldnot vbe a departure from the spirit of my invention and that the termsdenoting parallelism used in this specification and in the claims areused in a sense broadly covering such deviations from the theoreticalparallelism and would not render the machine inoperative.

I have provided a hand-wheel on a projecting portion of the shaft 10,kwhereby the Amoving arts of the machine may be operated to tacilitatethe adjustment of the sev- Y A eral parts.

The stock-bed B is bolted to the trame A and is removable and maybesubstituted by other stock-beds, havingstock-guides 2, oonforning todifferently-coniigured stock. So, also,.may the tool-beds 45 besubstituted by others adapted to differentv work. Whendifferently-configured stock isto be operated u' on, the feed-rolls andpressure-rolls shouldv a so be substituted by others adaptedfor theparticular class of work. In the claims.
